Abstract

The low-temperature catalytic ozone oxidation of benzene was investigated. In this
study, Al-SBA-16 (Si/Al = 20) that has a three-dimensional cubic Im3m structure and
a high specific surface area was used for catalytic ozone oxidation for the first
time. Two different Mn precursors, i.e., Mn acetate and Mn nitrate, were used to synthesize
Mn-impregnated Al-SBA-16 catalysts. The characteristics of these two catalysts were
investigated by instrumental analyses using the Brunauer-Emmett-Teller method, X-ray
diffraction, X-ray photoelectron spectroscopy, and temperature-programmed reduction.
A higher catalytic activity was exhibited when Mn acetate was used as the Mn precursor,
which is attributed to high Mn dispersion and a high degree of reduction of Mn oxides
formed by Mn acetate than those formed by Mn nitrate.
